GB/T42558.3—2024

引言

直流输电是实现高电压、大容量、远距离送电的重要手段，受制于电源位置、环境等因素，部分站点

建于高原区域，具有高海拔、高电压等级特征，与低海拔同型电气设备相比，在结构、高度、长度、质量方

面有明显差异，体现为更高、更长、更重、更柔，对高地震烈度区设备的抗震性能提出更严苛的要求。为

使该类换流站电气设备的抗震设计、建模计算、试验及评估有所遵循，特制定GB/T42558《高原用换流

站电气设备抗震技术》。

GB/T42558拟由六个部分构成。

——第1部分：抗震试验及评价导则。目的在于确立适用于高原用高地震烈度区域换流站内电气

设备抗震试验的总体要求及评价原则。

——第2部分：抗震设计规范。目的在于规定高原用换流站内电气设备抗震设计总体要求、电气

设备的抗震设计、设备耦联连接的抗震设计、设备抗震构造措施。

——第3部分：减隔震设计规范。目的在于规定高原用换流站内电气设备的减震和隔震设计计算

方法、减震和隔震装置选择、构造要求。

——第4部分：设备选型规范。目的在于指导高原用换流站内电气设备的选型，提升电气设备的

抗震性能。

——第5部分：设备运维导则。目的在于为运行人员更好地开展高原用换流站内电气设备的监

测、巡视、评价、检修运维等工作提供标准依据。

——第6部分：地震监测系统技术规范。目的在于规定高原地震监测系统的适用范围、监测对象

与布设、监测系统的组成与技术要求、监测系统的测试、安装与验收、监测系统的管理与维护、

监测记录的存储与处理要求。
